Actually, from the Unova games onwards, Pokemon at Lv. 100 can still gain EVs. This is carried here such that all Pokemon with maxed out levels (according to the level cap in-force) still acquire EVs until they are maximized.

I remember months ago someone spread a false rumour of this item being available here on PBB though.
